摘要
当声表面波叉指换能器的指条重叠包络按照小波函数的包络设计时,得到的声表面波叉指换能器脉冲响应函数等于小波函数,从而制造出了声表面波式小波变换器件。本文提出了利用两只声表面波式小波变换器件构造小波变换重构器件的新方法。对器件误差的来源作了分析,提出减小误差的方法。
When we design the fork overlap envelope of the SAW inter-digital energy converter according to the envelope of the small wave factor, we got that the pulse response factor of the SAW interdigital energy converter is equal to the small wave factor, so that SAW small wave energy converter device is made. The paper points out a new method of using two SAW small wave energy converters to make small wave converter restructing devices. The reason for the device error is analyzed and the method for reducing the error is presented.
